Bug: data mobile interface looses ip

@domubpkm said in Bug: data mobile interface looses ip:
The simplest solution is to turn off the cellular data and turn it back
Yes I know but this is a workaround not a real solution, it's not convenient at all, especially if you expect to receive notifications Internet needs to run always in background without manual action. Especially in the context of VoLTE I wonder what impact it has on incoming calls.

totally agree
I don't know if this currently has an impact on telephone communications since I can call and receive calls with disconnected cellular data. And for 4G calls, Volte is not working for me currently.

By the way I've just noticed something else strange in the logs:
sometimes I have 2 interfaces called "ccmni1" and "ccmni2". But sometimes I have "ccmni0" and "ccmni2" . I'm not sure if it is related to this bug or not, as both possibilities seem to be able to work if the interface has proper IP. -
Actually I have had the bug once again, and this time the interface holding the IP "ccmni0" was down, but forcing it up did not restore the connexion, I could ping the gateway but nothing more.

I'm wondering about something, as this problem is an IP loss problem, I think it should be noted that by defualt NetworkManager uses it's internal dhcp handler. But it is also possible to configure it to use dhclient. And I wonder if the later would not be more reliable.
So I think I will test to change the configuration of my NetworkManager to use dhclient, and see if it has any impact on this bug.

Any news about this annoying issue ?
-
I will soon try to write a workaround script, but when I have time.

@pparent THANKS. I still linked this post to NotKit from the Volla team. This is still a big problem for the Volla 22 which will have to be fixed. In addition, network loss is almost systematic each time the volla 22 is restarted.
-
I've written a workaround script that I'm currently testing, that detects an IP loss on the interface and automatically reinitialize the modem when it happens. For now it seems to work quite well, and even seems to have a positive impact on VoLTE connexion. I will test it for a few days, and if everything goes well, I will publish it here.

@pparent Great.
A good test is to see if the connection is still lost after reboot or complete shutdown and startup.
